To Vall whom t may concern Be it known that I, PEARL K. CRoWnLL, a citizen of the United States, residing at San' VOne object of the invention is to provide mechanism whereby cotton, usually lint cotton, may be supplied continuously from any ordinary cotton condenser, feeder or similar means and progressively tamped or tramped to'more eifectually drive out the air from the cotton lint thanheretofore.

Another object of the invention is to so construct a preliminary/'cotton tramper and presser and an ultimate cotton baler that the partially pressed cotton may be delivered or Atransferred from the preliminary machine tothe ultimate machine without handling Vthe same and in whichthe'cotton tramper is adapted to assistl in such transfer.

Another object of the invention is to soV construct a cotton tramper boX for a cotton baler that the cotton lint is continuously de livered at the point at which is tobe' tramped and is confined at the sides 1n the progressive formation of the preliminary orV tramped bale. Y

Another objectof the invention is to so construct a combined vcotton tramper and baler or compressor that the tramped cotton or preliminary bale may be delivered vertically into the bale compressor and that the weight of the cotton may assist in such move.- ment of the preliminary bale.

Other objects of the invention will appear from the following description. v

The invention consists inthe combined tramper and baler hereinafter described and claimed. I i

In carrying this invention into practice'it Similar characters of reference designate is lmy purpose first to continuously supply s cotton to the tramper and to tramp saidcotton as it reaches a suitable point whereby the tramper member or plunger acts against a comparatively `small amountof the loose cotf readily driven v out 'of the loose cotton and.

said cotton is more closely packed. .During such tramping process. the tramping mech- 80 ton and compresses the same against the anism and certain members of the lint cot- 'i ton delivery means rides upward, as the height to the bale increases, so thatthe weight of some of vsuch means or mechanism acts against the compressed cotton.

When the desiredy amount of cotton lint v' has thus been trampedand shaped to form the preliminary bale'said bale is deliveredV 1 vertically, and preferably downwardly, into the boX of a compressor, of any suitable construction which is adapted to subject the preliminary bale to thepressure found to bel necessary or desirable to compress the b'ale to the predetermined dimensions.y While such second, or ultimate, compression-of. the

bale is taking place the tramper mechanism is or may be operating on another supply of the cotton lint,

As shown in the drawings, in its preferred form, 10 is a suitable base or foundation having the guide 11 for the plunger 12 having the head 13 of any well known mechanism for moving said plunger 12 vertically with' the desired lpressure. Usually this plunger` 12 and its head 13 will form part of some hydraulic compressor mechanism which, in itself, forms no part of the present invention. Mounted on the foundation 10 are the standards 14, 14 of any suitable size and strength to sustain the mechanism associated therewith.

The standards 14, 14 have the bearings 15, 15 in which the cross timbers 16, 16 of the side walls 17, 17 of the compressor box are mounted to rotate so that the upper ends of said walls 17, 17 or of one of said walls may be swung outward to permit the removal of a bale. The upper portion of the walls 17, 17 having the members 18, 18 which, when a bale is being compressed, are held from outward movement by the tie rods 19, 19 of any usual and well known construction for such purpose. These tie rods are of course located outside the compressor box and preferably as indicated at 19, 19 Fig. 2. In view of the fact that the bale is formed and compressed to a considerable degree in the tramper ,or press box the compressor box vneed not necessarily be provided with vertical walls other than the walls 17, 17.

At the upper portions of the standards l14,

14 are mounted the girder members 20, 2O and 21, 21 securely bolted together of which members 21, 21 have the flanges 22, 22 which form a track for the wheels 23, 23 of the platen 24 which latter is of strong and substantial construction and is adapted to be moved or traversed along said track toward and from stop 21 by means of the racks 25, 25 pivotally connected with said platen and operated by means of the pinions 26, 26 of the shaft 27 which has the balance or hand wheel 28 and is journaled in bearings of the frame girder members 29, 29 and 30, 30 which are .firmly secured in place* and, prefeiibly, rest on the girder members 20, 2O

and.21, 21 respectively in such manner that the .flanges 31, 31 of the members 30, 30 ex- ,tend inward and overlap the upper edge portions of the platen 24 to resist positively the upward movement of said platen against pressure applied therebeneath. In order to operate shaft 27 by power when desired said shaft is supplied with the clutch 32 of any well known construction.

The frame girder members 30, 30 have the rails 33, 33 on which the wheels 34, 34 of the carriage 35 are free to travel. This carriage 35 is'caused to move back and forth preferably by the mechanism shown in the drawings in which the tongues 36, 36, pivotall'v connected with the carria ge 35 are supported at their outer ends by the roll-er bearings 37,

37 of the machine frame and are provided with the shaft 38 having the sleeve 39. Journaled in bearings of the girder members 29 and 30 are the shafts 40 and 41 having respectively the oppositely extending cams 42 and 43 adapted to act alternately on said sleeve 39. Shaft has the gear 44 which drives the gear 45 on shaft 41 and said shaft 41 in a direction opposite to that in which shaft 40 is rotated and motion is transmitted to said shaft 40 through its gear 46 by gear 47 of shaft 48 which is driven in any usual manner.

Carriage 35 has the curved guide 49 having the extension 50 and on said carriage 35 is mounted a frame comprising the uprights 51, 51 and 52, 52 suitably braced and connected andthe standards 53, 53 spaced apart while to the uprights 52, 52 are secured the guide plates 54, 54 which at their lower ends are curved as at 55 to correspond with the guide 49 from which said ends are spaced. The ends of the tramper box formed between the standards 53, 53 and the guide plates 54, 54, and the closure device hereinafter described, are defined by the members 56, 56 mounted on said carriage 35 which may be of any usual construction to confine the cotton lint. The hase orr bottom of this tramper is formed by the platen 57 which has a series of rollsV 58, 58 riding` on the platen 24. Provision is made to limit the movement of platen 57 in one direction, toward the left hand as shown in the drawings, by mounting the angle iron 59 at the lower portion of carriage 35, whereby a portion of said angle iron extends to a point to intercept said platen 57 and said platen is usually locked to said angle iron by the spring latches as 60 mounted on the sides of said 4platen and engaging` the ends of said angle iron as indicated in Fig. 6. A cross plate 61 has the ears y62, 62 carrying pivoted links 63, 63 at the lower ends of which is the shaft 64 having cam shaped ends which may 'be brought between the bevel ends of said spring latches as 60 to spread said latches to release them from the ends of said angle iron 59 so that the platen may move away from said angle iron when, in the movement of platen 24, the upstanding member 65 of platen 24 engages platen 57.

Extending upward from the girder memn bers 29, 30 are the guide standards 70, 70 connected at the tops by the cross member 71 and having the guides 72, 72 furnished with the stops 73, 73. Slidable on said guides 7 2, 72 is a cross head comprising the members 74, 74, 75, 75 ywhich is adapted to be limited in its downward movement by said stops 73, 73, Mounted on the members 74, 74 of said cro-ss head is the vertical wall 76 of the cotton feed chute which has the side walls 77, 77 extending inward between the guides 54, 54, the back wall 78 spaced from said wall 76 and they inclined wall or apron 79 spaced from the lower lend of wall 76 whereby cotton lint passing down over' guides 82, 82- on which is slidable a closure curtain of strong and durable construction` comprising the series of bars 83, 83 which are connected together, and t0 said guides 82, 82 by links so that said bars 83, 83 are free to follow in the space between they curved guides 49 and 55 in the up and down movement of the chute. Said bars 83, 83 are of such length that their ends are overlapped by the guides 54, 54 whereby as the feed chute moves upward said bars close the space between said guides 54, 54 and form one wall of the tramping box.

Mounted on the cross head members 74, 74 is the cylinder 84 which is of any usual construction adapted, when supplied with pressure fluid, to effect the reciprocation of the piston rod 85 having the tramper head V86 which operates to` drive downward supplied from the apron 79, through 'the opening between said apron and the wallV 78 and to compress or consolidate `said cotton. Preferably the tramper head 86 is slidably engaged with guides as 87 of the walls 77, 77, see Fig. 3, but I do not desire to limit myself to the particular construction of the tramper or plunger shown herein or to the manner in which it is slidably mounted.

While the baling machine forming. ther subject'matter of this invention is adapted to bale other ber or material than cotton the machine is especially useful in baling cotton which is deliveredl to the apron79 of the feed chute as lint from a condenser or from any suitable feeding device.

When delivered to the apron 79 from a condenser, so called, the cotton ber lis usually extremely loose and light and is in shape somewhat of a lap but such shape or formation is not necessarily maintained and said lap may become folded o'rfdistorted in shape in moving down the inclined surface of said apron 79. Y i In the operation of the machine shaft 48 is driven in any well known manner and motion from said shaft isv transmitted through gears 47, 46 to'shaft 40 and thence though gears 44, 45 to shaft 41 so that shafts d 40 and 41 rotate in opposite directions and their cams 42, 43 act alternately on the sleeve 39' of shaft 38 carried bythe arms cotton,

36, 36 of carriage 35 to effect the reciprocation of said carriage and the yparts mounted thereupon or engaged therewith at the time,

which includes the frames having the stand- V y ards 5land uprights 52, 53, the latter having the guides 54, and the curtain formedy bythe barsV 83, 83 as the suspending devices f at the upper end of saidcurtain are free to move on their guides 82, 82. Platen 57 is at this time locked to the ends of `angle'iron 59 by its latches `60 and hence moves with said carriage 35. The preliminary bale forming compartment or press box hence is defined between the sides 56, 56 and the ends formed respectively by the series of uprights 53, 53 land the curtain comprising `the bars 83, 83 while the 'platen 57 forms the bottomV of said compartment or box or the resistance means against which the cot- .tonis packed.

Such lateralV movement ofthe tramper box or press box is of course relative to the tramper or plunger 86 and is also rela" tive to the feed. chute ,or cotton delivery but it is evident' that such relative movement between said box and the tramper and cottondel'ivery mechanism be accomplished by effecting the lateral movement ofpressv box, and it is not my intention to limit this porltion of my invention except in so far that,

preferably, 1 do effect some lateral relative movement between the press box and one or more ofthe elementswhereby the fiber is delivered to and'compressed insaidbox.

In the machine herein shown, during the reciprocation of the ,carriage 35 and the Vparts attached thereto or detachably connected therewith the tramper or plunger 86 is operated verticallyrwith an up and down movement at a `suitable speed and under suitable pressure, therefore when said tramper is in its elevated position, "shown approximatelyA in Fig. 4, a .portion of the cotton lint on the apron 79 may slide downward on to-the platen 57 and will receive the impact of tramper 86 on the next down- Ward movement ofl said tramper. This.

operation will be repeated during the traverse of the platen 57 and the parts related thereto until a complete layer of lcotton has been supplied in comparatively small quan-l tities to said platen and compressed to some extent.v On the'reverse movement of said platen 57- thesame process is repeated and the irst layer ofcotton will be additionally compressed by the action of tramper v86 on the cotton forming said second layer, and j then the preliminary bale'will be built up in a successionbf layers between the members 53 and the vertical wall of guide 49.

As the cotton is built [up on platen 57 said cotton will eventually bear against they bottom of base 81 of the chute or deliveryV device which .therefore will rise with the built up cotton and will bear t0 50m@ GXQH on the top of said cotton and tend to compress those portions of the cotton on which it bears so that the cotton is under constant pressure. By' reason of the action of the tramper on successive comparatively small charges or amounts of cotton said charges become, to greater extent than heretofore, felted with the adjacent charges so that the preliminary bale, as a whole, is more condensed than heretofore and is less liable to expansion.

After the preliminary bale thus formed has reached the desired height or contains the predetermined amount of cotton it is usual to compress said bale and for such purpose the bale is preferably to be delivered to the compress box and ordinarily the operation of the tramper may cease during such delivery of the preliminary bale which, in this machine, requires but a very short time usually less than a minute.

The walls 17, 17 of the compress box being in the upright position the movement of carriage is arrested with platen 57 in the position shown iny Fig. 1. Shaft 64: is now brought between the spring latches of said platen to release said latches from the angle iron 59; power is now applied to rotate shaft 27 whereby the pinion 26, 26 of said shaft act on the racks 25, 25 to draw platen 211 from its position above the compress box and, in such movement, member of said platen 24: engages platen 57 and moves said'platen 57 in the same direction thus opening the passage between the press or tramper box and the compressor box. Usually, when said platens 24 and 57 are thus drawn out of its path, the preliminary bale will move downward by gravity, of its own weight and the weight of the chute, but, if necessary, the tramper 86 may be operated to drive downward said preliminary bale between the walls 17, 17 of the compressor box.

The rotation of shaft 27 is now reversed and platens 2li and 57 are moved back to position shown in Figs. 1, 2, f1 and 5 and the latches 60 of platen 57 engage again with angle iron 59 while the edges of platen 24 are located beneath the flanges or members 31, 31 of girder member 30 so that said platen is held against upward pressure. The compressor mechanism or plunger head 13 is now operated inV any usual manner `to effect the compression of the bale between said head and the under side of the platen 211, the compressed bale is strapped to hold it in shape and said bale is removed by releasing the ties 19, 19 and swinging out the upper end of one of the walls 17 which swinging with its member 16 forms an incline to the yfloor A, A.

During the operation of the compressor member 13 on the bale between the walls 17, 17 another preliminary bale may be formed above the platen 57 as above described so that the tramping yand compress ing are practically simultaneous. As soon as one preliminary bale is completed in the tramper said bale is delivered to the compressor and the formation of another preliminary bale is commenced.
